Electrical Tools and Equipment
 Electrical task can be accomplished systematically to save
time, effort, and resources. Most of the work cannot be done
using bare hands. To do the task, electrical tools or
equipment are needed to perform the job.

 The following are common electrical tools
and equipment needed in the installation of
electrical wiring.
 I. SCREW DRIVERS. These tools are made of steel
hardened and tempered at the tip used to loosen or tighten
screws
 A. Standard/Flat Screw Driver. The blade tip is wedge-
shaped and resembles a negative (-) sign. This is used to
drive screws with a single slot head.
 B. Philips Screw Driver. This has a cross tip resembling a
positive (+) sign. This is used to drive screws with cross slot
heads.
 C. Stubby Screw Driver. It comes in either Standard or
Philips screw driver with short shank or blade and a shorted
handle used to turn screws in tight space where standard
screw driver cannot be used.
 D. Allen Screw Driver/Wrench. This could be in the shape
of a screw driver or a wrench. Its function is to drive screw
with hexagonal slot head.
 II. HAMMERS. These are tools used in driving or pounding
and pulling out nails. They are made of hard steel, wood,
plastic or rubber. The following are types of hammer:
 A. Claw hammer
 B. Mallet(rubber head)
 C. Ballpeen hammer
 III. PLIERS. These made from metal with insulators in the
handle and are used for cutting, twisting, bending, holding,
and gripping wires and cables.
 A. Combination Pliers (Lineman’s Pliers). This is used
for gripping, holding, and cutting electrical wires and
cables and even small nails. They are usually used by
linemen in doing heavy tasks.
 B. Side Cutting Pliers. This type of pliers is used for cutting
fine, medium and big wires and cables.
 C. Long Nose Pliers. This is used for cutting and holding fine
wires. This can reach tight space or small opening where
other pliers cannot reach and also used in making terminal
loops of copper wires.
 IV. Wire Stripper- A tool
used for removing
insulation of medium
sized wires ranging from
gauge #10 to gauge #16.
 V. Electrician’s Knife.
This is used by linemen
to remove insulation of
wire and cables in low
and high voltage
transmission lines
 VI. Portable Electric
drill. A small drilling
machine with a chuck
capacity of ¼‖ to 3/8‖. It
is used in making holes
on metal sheets and
concrete walls.
 VII. Hacksaw. This tool is
used to cut metal conduit
and armored cable
Electrical Supplies and Materials
 Electrical materials are developed and constructed for a
special purpose such as to:
 1. control the flow of current in an electrical circuit;
 2. carry electrical current from the source to the load or
current consuming apparatus;
Electrical Supplies and Materials
 Electrical materials are developed and constructed for a
special purpose such as to:
 3. hold and secure wires to its fixtures inside and outside
houses and buildings; and
 4. protect the houses, buildings, appliances’ and
instruments from any destruction and damage.
 The following are the most commonly used
electrical materials.
 Convenience outlet- a device that acts as a convenient
source of electrical energy for current consuming appliances.
It is where the male plug of an appliance is inserted and
usually fastened on the wall or connected in an extension
cord.
 It maybe single, duplex, triplex or multiplex and could be
surface type or flush type.
 Male plug- a device inserted to a convenience outlet to
conduct electric current. A flat cord is attached to it on one
end and the other end is connected to a current consuming
instrument or appliance.
 Lamp holders- devices that hold and protect the lamp and
are also called as ―Lamp Sockets/Receptacles‖. These
come in many designs and sizes.
 They are classified as flush, hanging (weather proof/chain)
and surface types.
 Switch - a device that connects and
disconnects the flow of electric
current in a circuit.
 There are many shapes, designs,
and types and they are classified as
hanging, flush, and surface types.
 Fuse - a circuit protective device that automatically blows and
cut the current when and over load or short circuit happens.
 Circuit Breaker - a protective
device used to automatically
blows and cuts the current when
trouble in the circuit such as
short circuit or overload occurs.
 Junction Box - an octagonal
shaped electrical material where
the connections or joints of
wires are being done. It is also
where the flush type lamp
holder is attached. This could
be made of metal or plastic
(PVC) Polyvinylchloride
 Utility Box - a rectangular
shaped metallic or plastic (PVC)
material in which flush type
convenience outlet and switch
are attached
 Flat Cord- Is a duplex stranded
wire used for temporary wiring
installation and commonly used
in extension cord assembly.
 Electrical Wire/Conductor- electrical
material that could be:
 a. Stranded wire which is made of multiple
strands joined together to make a single wire.
 b. Solid wire is made of a single strand of
copper or aluminum wire. These are used in
wiring installation inside and outside the
buildings.
 Conduits/Pipes- electrical materials
used as the passage of wires for
protection and insulation. These could be
 rigid metallic, flexible metallic conduit
(FMC),
 rigid nonmetallic (PVC), and
 flexible non-metallic or corrugated
plastic conduit (CPC
 Clamps- electrical materials used to hold and anchor
electrical conduits in its proper position
 Connectors- used to attach metallic or non-metallic conduit
to the junction or utility boxes.
 Direction. Identify each of the following tools/materials
 Pliers. They could be with insulated or uninsulated handles.
The Electrician’s Tool Pouch
 The Electrician’s tool pouch is essential in
that it helps kept electrical tools organized.
The tool pouch allows the right tools at
hand which makes the job more efficient.
 The electrician must have proper tools for

the job.
 Tools must be maintain and kept in good

working condition.
 Certain tools are essential, and without

them the electrician should not attempt to

Rules for care of hand tools
 There are many more hand and power
tools that electricians will use in
residential and commercial wiring.
 All tools should be used only for the
purpose intended.
 It is the electrician’s responsibility to keep
his or her tools sharp, clean, and
lubricated.
 A well maintained tool has a longer life
and is safer than an improperly
maintained tool.
 Repair tools when possible, but discard
worn or damaged tools.

Factors For Purchasing Tools
Factors to consider when purchasing

tools are size, design, and quality.
 Always purchase the correct sized

tools for the work to be done.
 Tools should be designed specifically

handles, hammers with straight claws.
 The purchase of quality tools last
longer which saves replacement cost.

Remember
 Select the right tool for the job.
 Keep tools clean, lubricated, and in good working condition.
 Purchase good quality tools they are safer and will last longer.
 Repair tools when possible, but discard worn or damaged tools.
